Use system recommendations to introduce security
Essential authorizations and parameters in the SAP® environment
Trace after missing permissions: Run the System Trace for Permissions (ST01 or STAUTHTRACE transaction) to record permission checks that you want to include in the role (see Tip 31, "Optimise Trace Evaluation"). Applications are logged through the Launch Permissions checks.
The assignment of combinations of critical authorizations (e.g., posting an invoice and starting a payment run), commonly known as "segregation of duties conflicts," must also be reviewed and, if necessary, clarified with those responsible in the business departments as to why these exist in the system. If compensating controls have been implemented for this purpose, it is helpful if the IT department also knows about this so that it can name these controls to the IT auditor. The IT auditor can then pass this information on to his or her auditor colleagues.
Manual authorizations
System users are also intended for anonymous access. They are used in technical operations that require a user, such as batch runs or RFC connections. With them, therefore, no dialogue login is possible on the SAP system, but only the login via RFC call. Multiple logins are always possible for a system user, and the password modification rules (see also the explanation under "Service Users") do not apply. The password of a system user always has the status Productive and can only be changed by the user administrator.
The general authorizations are quite normal authorization objects in SAP HCM, which regulates the access to PA/PD infotypes (tables PAnnnn / HRPnnnn), clusters for the own person or for other persons. Typical authorization objects are "P_PERNR", "P_ORGIN", "P_ORGXX", "PLOG" and "P_PLCX".
Assigning a role for a limited period of time is done in seconds with "Shortcut for SAP systems" and allows you to quickly continue your go-live.
Once a permission concept has been created, the implementation in the system begins.

This can also be done with the transaction PFUD (see comments to the article "SAP BC: Empty user buffer" :-).
